ROAD-ROLLER.

To all whom it may concern:

Be it known that I, JAMns C. FINDLAY, a citizen of the United States,residing at Marquette, in the county of Marquette and State of Michigan,have invented certain new and useful Improvements in Road-Rollers, ofwhich the following is a specification.

This invention has for its object to provide a snow or road rollerin-which the roller or drum is in sections which are adjustable relativeto each other so that a flat, convex or concave road-bed may be formed.

The invention also has for its object to provide a structure whichprevents skidding or end slipping to the sides of the road.

A further object of the invention is to provide a novel construction andarrangement of parts to be hereinafter described and claimed.

In order that the invention may be better understood, reference is hadto the accompanying drawings forming a part of this specification, inwhich drawings- Figure 1 is a plan view of the machine, partly brokenaway and in section. Fig. 2 is a side elevation thereof. Fig. 3 is afront end view partly in section.

Referring specifically to the drawings, the frame of the machinecomprises longitudinal side bars 5 connected at their ends by cross bars6, said bars being arranged to form a rectangular open frame in whichthe rollers or drums 7 are mounted. The side andcross bars may beordinary L-beams as shown.

Three rollers 7 are provided which are arranged side by side and extendtransversely of the machine. An independent axle 8 is provided for eachroller but said axles are connected. The axle of the middle roller ismounted at its ends in fixed bearings 9 carried by bars 10 extendingbetween and se cured to the cross-bars 6, and said axle is connected tothe axles of the end rollers by knuckle or universal joints 11. Theouter ends of the axles of the end rollers are supported in bearingscarried by the side bars 5, said bearings having eccentric or take-upboxes 12 so that the said axles of the end rollers may be raised orlowered and thus thrown out of axial alinement with respect to the axleof the middle roller so as to extend at an angle thereto. This verticalad-- Specification of Letters Patent.

rollers are raised relative to the midde roller, a concave road-bed ismade,and when lowered, the road-bed is made convex. Upon adjusting theaxles of the end rollers so that all three rollers are in axialalinement, the road-bed is made fiat. Thev eccentric boxes 12 areprovided with levers 13 for making the hereindescribed adjustments. Thecrossbars 6 carry arched beams 14 on which the drivers seat 15 and footrests 16 are mounted.

A draft tongue 17 and other suitable devices for attaching the draftanimals are provided, said draft attachment being mounted on eithercross bars 6 -so that it may be reversed as shown by dotted lines inFig. 2. The cross-bars 6 also carry scrapers 18 for removing mud, dirt,snow, etc., which may stick to the rollers 7.

In order to prevent the machine from skidding or slipping endwise to thesides of the road, the periphery of the middle roller 7 has anoutstanding flange 19 at each end.

The machine herein described is simple in construction and highlyetficient in operation, and it effectually serves the purpose for whichit is designed, and by providing for the adjustment of the end rollers,the roadbed may be rolled flat, convex or concave as desired.

I claim:

1. A road-rolling machine, comprising a supporting frame, a jointedsectional axle comprising end sections and an intermediate section, theend sections of the axle being vertically adjustable and theintermediate section being fixed, and rollers carried by the respectiveaxle sections.

2. A road-rolling machine comprising a supporting frame, a jointedsectional axle comprising end sections and an intermediate section, afixed bearing for the intermediate axle section, vertically adjustablebear ings for the end sections of the axle, and rollers carried by therespective axle sections.

3. A road-rolling machine comprising a supporting frame, a jointedsectional axle comprising end sections and an intermediate section, theend sections of the axle being adjustable to extend in axial alinementwith the intermediate section or at an angle thereto, and theintermediate axle section being fixed, and rollers carried by therespective axle sections.

4. A road-rolling machine, comprising a supporting frame, a jointedsectional axle comprising end sections and an intermediate section beingfixed, and rollers carried by the respective axle sections, and a draftattachment connected to supporting frame and reversible thereon.

" In testimony whereof I afiix my signature in presence of twowitnesses.
